Glucose Readings
Q. Why is my sensor reading dierent from my blood glucose meter
reading?
A: The Eversense CGM System measures glucose in interstitial fluid
(ISF) between the body’s cells. Physiologic dierences between ISF
and blood from a fingerstick may result in dierences in glucose
measurements. These dierences are especially evident during times
of rapid change in blood glucose (e.g., after eating, dosing insulin, or
exercising). On average, glucose levels in ISF lag behind glucose levels
in blood by several minutes.
Q: I am getting “-- -- --” in place of sensor glucose readings on
the app.
A: You may not get any sensor glucose readings when there is no
connection between your smart transmitter and your sensor or smart
transmitter and mobile device.
